LIFTING-MACHINE Specification of Letters Patent.

Patented Nov; 12, 1907.

Application filed J'ulv 10. 1907. Serial No. 383,078.

To all whom it may concern:

Be it known that I, CARL MoLLnR, a citizen of the United States, and a resident of Jacksonville, in the county of Duval and State of Florida, have invented a new and. Improved Lifting-Machine, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved lifting machine, which is simple, durable, and portable in'construction, and more especially de signed for picking up barrels and other packages from the ground or floor and elevating and discharging the same at any desired height for storing, stacking and other purposes.

The invention consists of novel features and parts and combinations of the same, which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of the improvement; Fig. 2 is a side elevation of the same, and Fig. 3 is a sectional side elevation of the same on the line 33 of Fig. 1.

The improved lifting machine is mounted on a suitably constructed framework A provided with wheels or casters B, to permit of conveniently moving the machine about from one place to another. On the framework A is secured an incline or skid G on which the barrels or other packages D are rolled or pushed up the said incline or skid 0, extending from near the ground or floor to a landing E, on which the barrels or other packages D are discharged after leaving the upper terminal of the incline O.

The barrels or other packages D are moved up the incline G by the use of pairs of arms F, F, F preferably provided at their free ends with friction rollers F said pairs of arms being secured on transversely extending shafts G, G, G respectively, journaled in suitable bearings on the framework A, the said shafts extending in a plane approximately parallel to the incline O, as plainly indicated in the drawings. On the shafts e, G, G are secured gear wheels'H, H, H of which the gear wheels H and H are connected with each other by an intermediate gear wheel H", and the gear wheels H and II are connected with each other by an intermediate gear wheel H, so that when one of the shafts is rotated the others rotate in unison with it. The gear Wheel H is in mesh with a pinion I secured on a shaft I journaled in suitable bearings arranged on the framework A, and on the said shaft 1 is secured a gear wheel I in mesh with a pinion J secured on the shaft J" extending transversely and journaled on the framework A. On the shaft J is secured a pulley K connected by a belt K with a pulley K secured on the shaft L of a motor L mounted on the framework A and of any approved construction. Now when the motor L is running a rotary motion is transmitted by the belt K and the pulleys K K to the shaft .T by the pinion .T, and the gear wheel I and pinion I rotate the gear wheel H which by the intermediate gear wheels H 11 turns the gear wheels 11, H to cause the several shafts G, G G to rotate in unison with each other and in the same direction. Now when the shafts G, G, G are rotated as described, the pairs of arms F, F, F are caused to swing around, and the said pairs of arms are so arranged one relative to the other to successively act on the package D to push the same up the incline C: that is, the lowermost pair of arms F engages the package D resting on the floor or ground at the beginning end of the incline C (see Fig. 3) so that the said arms F push the package D up the incline a distance until the friction rollers F of the said arms F move off the package at the top thereof. Immediately previous to this taking place, however, the other or next following pair of arms F has engaged the package and now pushes it further up the incline O, and immediately previous to the arms F leaving the package D, the next following arms F take hold of the package and push the same further up the incline and finally off the upper terminal of the incline onto the landing E.

Although I have described three lifting arms, it is evident that any desired number of such lifting arms may be used according to the length of the incline C, it being understood, however, that a pair of arms engages the package previous to the receding arms releasing the package. As illustrated in Fig. l the succeeding pairs of arms F, F and F are arranged in different Vertical planes so as to readily pass each other when swinging around.

If desired the incline C may be provided with friction rollers which insure an easy upward movement of the package without the expenditure of much driving force.

The lifting machine shown and described is very simple and durable in construction and can be conveniently moved about from one place to another, to allow of readily stacking barrels and the like or lifting other packages from one level to another level.

It is understood that I do not limit myself to the particular driving mechanism shown and described, as the same may be varied without deviating from the spirit of the invention and. instead of a pair of arms on each shaft, 21. single arm or more than two arms may be used to accomplish the desired result.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A machine for lifting packages comprising an incline for the packages to travel on, and sets of revolnble arms operating in conjunction with each other, said arms being arranged in different vertical planes and having their axes arranged in a plane approximately parallel to the said incline, the lowermost arm being adapted to engage the package on the ground or floor and push the same up the incline, the next following arms successively, engaging the package immediately previous to the preceding arm releasing the package.

2. A machine for lifting packages comprising an incline for the packages to travel on, and a set of revoluble arms operating in conjunction with each other, said arms being arranged in different vertical planes and having their axes arranged in a plane approximately parallel to the said incline, the lowermost arm being adapted to engage the package on the ground or floor and push the same up the incline, the next following arms successively engaging the package immediately previous to the preceding arm releas ing the package, the uppermost arm being arranged to move the package up the last portion of the incline and to push the package off the upper terminal of the incline.

A machine for lifting packages comprising a framework, an incline thereon, a series of shafts journaled on the framework and extending ina plane approximately parallel to the said incline, a gearing for rotating the said shafts in unison, and pairs of arms secured to the said.

shafts and arranged relatively one to the other, to successively act on the package and push the same up the said incline. I

4, A machine for lifting packages comprising a framework, an incline thereon, a series of shafts journaled on the framework and extending in a plane approximately parallel to the said incline, a gearing for rotating the shafts in unison, and pairs of-arms secured to the said shafts and provided at their free ends with friction roll ers, the said pairs of arms being arranged relatively one to the other to successively act on the package and push the same up the said incline.

5. A machine for lifting packages comprising a framework, an incline therein, a series of shafts journaled on the framework and extending in a plane approximately parallel to the said incline, a gearing for rotating the said shafts in unison, a motor mounted on the said framework, a driving gear connecting the said motor with the said gearing, and pairs of arms secured to the said shafts and arranged relatively one to the other to successively act on the package and push the same up the said incline.

6v A machine for lifting packages, comprising a frame having an incline, a plurality of shafts mounted in the frame approximately parallel with the incline, means for operating the shafts, and a pair of arms on each shaft, the arms of one shaft being out of alinement with the arms of the adjacent shaft.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
